    Histological and Clinical Findings in Different Surgical Strategies for Focal Axillary Hyperhidrosis

    DERMATOLOGIC SURGERY, Issue 8 2008
    FALK G. BECHARA MD
    INTRODUCTION Although a variety of different surgical strategies for focal axillary hyperhidrosis (FAH) have proven effective, little is known of intraoperative and postoperative histologies of different surgical methods. OBJECTIVE The objective was to use pre-, intra-, and postoperative histologic findings to evaluate different surgical procedures for FAH in establishing a possible correlation between the interventions and clinical outcome. MATERIAL AND METHODS A total of 40 patients underwent surgery with 15 undergoing liposuction-curettage (LC), 14 radical skin excision (RSE) with Y-plasty closure, and 11 a skin-sparing technique (SST). Before surgery, density and ratio of eccrine and apocrine sweat glands were evaluated with routine histology. Further biopsies were taken directly after surgery in the RSE and SST groups and 1 year postoperatively in all patients. Additionally, gravimetry was performed, side effects were documented, and patients were asked to evaluate the aesthetic outcome of the surgical method by using an analogue scale. RESULTS Preoperatively, the mean density of eccrine glands was 11.1/cm2 compared to 16.9/cm2 apocrine glands (apocrine/eccrine ratio, 1.6). Biopsy specimen directly after surgery showed remaining sweat glands in 7/15 (46.7%) LC patients and in 4/11 (36.4%) of the SST patients. One year after surgery, sweat gland density was significantly reduced in the LC (79.1%) and the SST (74.9%) groups. In the RSE group, only scar formation was present. Gravimetry showed significantly reduced sweat rates 12 months after surgery in all groups (LC, 66.4%; SST, 62.9%; RSE, 65.3% [p<.05]). Most frequent side effects were hematoma (LC, n=3; SST, n=2; RSE, n=3), subcutaneous fibrotic bridles (LC, n=8; SST, n=3; RSE, n=0), skin erosion (LC, n=3; SST, n=4; RSE, n=0), focal hair loss (LC, n=9; SST, n=11; RSE, n=14), and paresthesia (LC, n=4; SST, n=3; RSE, n=5). CONCLUSION Histologic distribution and density of sweat glands were comparable to previous studies. All three surgical procedures evaluated are effective in the treatment of FAH. RSE and SST techniques are associated with a higher risk of side effects and cause more extensive scarring. However, one LC patient (n=1; 6.7%) did not respond to treatment. [source]


    Rhinophyma and Coexisting Occult Skin Cancers

    DERMATOLOGIC SURGERY, Issue 2 2001
    Michael E. Lutz MD
    Background. Although coexistent tumors have been reported in patients with rhinophyma, few reports have described the coexistence of rhinophyma and an occult infiltrating squamous cell carcinoma (SCC). Objective. Preoperatively and during rhinophymaplasty, recognition of subtle changes can suggest an underlying malignancy. Methods. A large infiltrating SCC was noted during electrosurgical rhinophymaplasty. Mohs micrographic surgery was performed to clear the tumor. Results. The patient was tumor-free with no evidence of recurrence at 1-year follow-up. Conclusion. In the evaluation of changing rhinophyma or subtle changes in tissue noted during rhinophymaplasty, physicians must consider the possibility of an underlying malignancy. [source]


    Effects of maxillary sinus floor elevation surgery on maxillary sinus physiology

    EUROPEAN JOURNAL OF ORAL SCIENCES, Issue 3 2003
    Nicolaas M. Timmenga
    In a prospective study, the effects of elevation surgery of the maxillary sinus floor on maxillary sinus physiology were assessed. Seventeen consecutive patients without preoperative anamnestic, clinical and radiological signs of maxillary sinusitis underwent sinus floor elevation surgery with iliac crest bone grafts. All patients were subjected to unilateral endoscopic examination of the maxillary sinus, taking of a biopsy specimen from the sinus floor mucosa, and collection of a sinus lavage-fluid aspirate. This triad of evaluations was performed immediately preceding the elevation procedure, and 3 months (at implant insertion) and 9 months (at uncovering of implants) postoperatively. All procedures were performed under general anesthesia. Preoperatively, three out of 17 patients showed pre-existing mucosal pathology endoscopically, while the 3- and 9-month results revealed the presence of mucosal pathology in four and two patients, respectively. The 3-month microbiological evaluation showed a significant increase in cultures with bacterial growth, while the 9-month culture results were comparable to the preoperative status of the maxillary sinus. Morphologically, neither fibrosis nor an altered inflammatory response or thickening of the epithelium and lamina propria was observed postoperatively. The number of goblet cells in the epithelial layer was increased. From this study it is concluded that the effect of maxillary sinus floor elevation surgery with autogenous bone grafts does not appear to have clinical consequences in patients without signs of pre-existing maxillary sinusitis.

    Longitudinal health-related quality of life after mandibular resection for oral cancer: a comparison between rim and segment,

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 1 2004
    Simon N. Rogers FDS
    Abstract Background. Mandibular resection for oral cancer is often necessary to achieve an adequate margin of tumor clearance. Segmental mandibulectomy has been associated with a poor health-related quality of life (HRQOL), particularly before composite free tissue transfer to reconstruct the defect. Little is published in the literature contrasting the subjective deficit of segmental compared with rim resection. The aim of this study was to use a validated head and neck HRQOL questionnaire to compare rim and segmental mandibular resection in patients having primary surgery for oral cancer. Method. There were 224 consecutive patients between 1995 and 1999 who were treated by primary surgery for oral squamous cell carcinoma. One hundred twenty-tree had no mandibular resection, 44 had a rim resection, and 57 had a segmental resection. The University of Washington Quality of life questionnaire (UW-QOL) was adminstered before treatment, at 6 months, 12 months and after 18 months. Results. Preoperatively, patients undergoing segmental resection reported significantly more pain, chewing problems, and a lower composite UW-QOL score. Postperatively, the segment group tended to score worse at all time points, particularly in appearance, swallowing, recreation, and chewing; however, the difference between rim and segment was only seen in smaller resections without adjuvant radiotherapy. Little difference was seen between rim or segment for tumors <4 cm with radiotherapy and between rim and segments for tumors >4cm. Conclusion: After segmental mandibulectomy and reconstruction using composite free tissue transfer, the UW-QOL scores were relatively good. The only 2 difference between rim and segments was noted in the small resections without radiotherapy, and some of this was reflected in differences at baseline. © 2004 Wiley Periodicals, Inc.

    Comparison of bone-anchored male sling and collagen implant for the treatment of male incontinence

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 9 2006
    RAHMI ONUR
    Aim: To compare the effectiveness of transurethral collagen injection and perineal bone-anchored male sling for the treatment of male stress urinary incontinence (SUI). Methods: Seventy-one men with SUI underwent either transurethral collagen injections (n = 34) or perineal bone-anchored male sling (n = 37) between June 1999 and October 2003. Most of the patients in each group had radical retropubic prostatectomy and/or external beam radiation therapy (EBRT) in relation to the cause of incontinence. There was one patient in both groups who only had EBRT for the cause. The mean duration of incontinence were 4.2 and 4.4 years, respectively. Collagen injections were carried out transurethrally either under regional or general anesthesia until co-aptation of mucosa was observed. The male sling was placed under spinal anesthesia with a bone drill using either absorbable or synthetic materials. Retrospectively, all patients were assessed for continence status and procedure-related morbidity, if present. The outcome of both procedures was also compared with the degree of incontinence. Results: Ten (30%) patients in the collagen group showed either significant improvement or were cured following injections. Preoperatively, the mean pad use in collagen group was 4.5 (SD 2.8) per day, whereas it was 2.2 (SD 1.1) after the injection(s). Collagen injection failed in 24 (70%) of the patients. Patients who received the male sling had a mean preoperative pad use of 3.7 (SD 1.5) and postoperatively, the number decreased to 1.6 (SD 1.2). Most of the patients in this group were either totally dry or significantly improved (n: 28, 76%). There was a statistically significant difference between two groups in respect to success rate (P < 0.05). Analysis of treatment outcome with the degree of incontinence revealed that the male sling is most effective in patients with minimal-to-moderate incontinence. Conclusions: Our results suggest that the male sling, a minimally invasive procedure, is more effective than collagen implant in the treatment of mild-to-moderate SUI in men. [source]


    Color Doppler sonography examination of partially obstructed kidneys associated with ureteropelvic junction stone before and after percutaneous nephrolithotripsy: Preliminary report

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2005
    SÜLEYMAN KILIÇ
    Abstract Aim: To evaluate resistive index (RI) changes before and after unilateral percutaneous nephrolithotripsy in chronic partially obstructed kidneys due to ureteropelvic junction (UPJ) stones. Methods: Intrarenal RI of obstructed and contralateral normal kidneys of 18 patients were recorded immediately before the operations and at postoperative days 1, 7 and 30. Postoperative RI measurements were compared with baseline values for all patients without grouping and separately for different groups according to the preoperative RI value of the obstructed kidney. Results: Mean age and symptom duration were 27.5 years and 43.8 weeks, respectively. Preoperatively and at all postoperative controls, kidney diameters and renal parenchyma thicknesses were normal in all patients. Mean RI of obstructed kidneys decreased from 0.68 to 0.63 for all patients (P = 0.032), from 0.64 to 0.63 for those with preoperative RI < 0.70 (P = 0.850) and from 0.73 to 0.62 for those with preoperative RI , 0.70 (P = 0.001). In patients with preoperative RI , 0.70 in obstructed kidney, significant RI decreases were recorded at postoperative day 7 and RI differences between obstructed and contralateral kidneys disappeared after then. No difference was present pre- and postoperatively between the mean RI of obstructed and contralateral kidneys of the patients with RI < 0.70. Mean RI of contralateral kidneys were normal preoperatively and showed no significant change postoperatively. Conclusions: Preoperative RI levels may indirectly reflect the presence of functionally significant obstruction in chronic obstructed kidneys related to UPJ stones. Patients with RI , 0.70 may have a good indication for a surgical approach. Normalization of high RI occurs rapidly after percutaneous nephrolithotripsy. [source]


    Pulmonary Embolectomy: Recommendation for Early Surgical Intervention

    JOURNAL OF CARDIAC SURGERY, Issue 3 2010
    Enisa M. Carvalho M.D.
    Despite all efforts at improving outcomes, there is no consensus on the management of acute severe PE. Methods: From May 2000 to June 2009, 16 consecutive patients underwent surgical pulmonary embolectomy at our institution. Mean age was 45 ± 17 years (range, 14 to 76) with nine (56%) males and seven (43%) females. Preoperatively, all cases were classified as massive PE; seven (43%) patients were in hemodynamic collapse and emergently underwent operation while receiving cardiopulmonary resuscitation. Results: There were nine (56%) urgent/emergent and seven (44%) salvage patients undergoing surgical pulmonary embolectomy. Of nine nonsalvage patients, seven (77%) patients presented with moderate to severe right ventricular (RV) dilation/dysfunction. Mean cardiopulmonary bypass time was 43 ± 41 minutes (range, 9 to 161). Mean follow-up duration was 48 ± 38 months (range: 0.3 to 109), with seven in-hospital deaths (43%): mortality was 11% (1/9) in emergent operations and 85% (6/7) in salvage operations. Conclusions: Surgical pulmonary embolectomy should be considered early in the management of hemodynamically stable patients with PE who show evidence of RV dilation and/or failure, as it is associated with satisfactory outcomes. Conversely, pulmonary embolectomy has dismal results under salvage conditions. Revision of current guidelines for the surgical management of this condition may be warranted.

    Ross Procedure for Aortic Insufficiency Due to Doubly Committed Subarterial Ventricular Septal Defect in Adults

    JOURNAL OF CARDIAC SURGERY, Issue 5 2005
    Ph.D., Shoh Tatebe M.D.
    Preoperatively, she developed congestive heart failure because of less compliance to oral medication, raising concerns regarding life-threatening thromboembolism if she undergoes mechanical valve replacement. Despite the pulmonary autograft being defective, there were no difficulties in completing the surgery. The defect of pulmonary autograft and the VSD was closed by an expanded polytetrafluoroethylene patch. She tolerated the procedure well and now enjoys improved quality of life. We present a discussion of the indication of Ross procedure in the rare presentation of congenital heart disease, as well as several issues raised in this case. [source]

    The present study was undertaken to identify the prognostic factors in such patients. Methods: We analyzed the data of 176 consecutive patients (161 men, 15 women), aged 29 to 88 years (mean 58.43), with a left ventricular ejection fraction (LVEF) <30% who underwent isolated coronary artery bypass grafting. The LVEF ranged from 15% to 30% (mean 27.18%). Preoperatively, 33% had angina, 19.9% had recent myocardial infarction, and 21.6% had congestive heart failure. The mean number of grafts was 2.5/patient. The intra-aortic balloon was used prophylactically in 20.5% of patients and therapeutically in 4.0% of patients. Results: The hospital mortality was 2.3%. The complications occurred as follows: perioperative myocardial infarction in two (1.1%), intractable ventricular arrhythmias in two (1.1%), prolonged ventilation in four (2.3%) and peritoneal dialysis in 1 (0.6%). The mean ICU and hospital stay were2.46 ± 0.76and7.57 ± 2.24days, respectively. The predictors of survival on univariate analysis were New York Heart Association (NYHA) class(x2 = 14.458, p < 0.001), recent myocardial infarction(x2 = 5.852, p = 0.016), congestive heart failure (CHF)(x2 = 5.526, p = 0.019), and left ventricular end-systolic volume index (LVESVI)(x2 = 25.833, p < 0.001). However, on multivariate analysis, left ventricular end-systolic volume index was the only independent left ventricular function measurement predictive of survival(x2 = 10.228, p = 0.001). Conclusion: Left ventricular end-systolic volume index is the most important predictor of survival after coronary artery bypass surgery in patients with severe myocardial dysfunction.(J Card Surg 2003;18:101-106) [source]


    Treatment of lumbar and lumbosacral spinal tuberculosis with minimally invasive surgery

    ORTHOPAEDIC SURGERY, Issue 1 2010
    Xi-feng Zhang MD
    Objective:, To evaluate the outcome of computed tomography (CT)-guided percutaneous puncture and local chemotherapy for tuberculosis (TB) of the lumbar or lumbosacral spine. Methods:, From January 2002 to August 2006, 49 patients with lumbar or lumbosacral spinal TB in whom conservative treatment had failed were treated by minimally invasive surgery. There were 21 female and 28 male patients. The mean age of the patients was 47 ± 18 years (range from 12 to 78 years). There were 40 cases with lumbar TB, and 9 with lumbosacral TB. From L1 to S1, the involved vertebral numbers were 8, 26, 19, 19, 21 and 10, respectively. In 3 patients the spinal TB involved a single vertebra, in 39 patients two, in 6 patients three and in only one case four vertebrae. According to the Frankel scale, three patients had grade E incomplete paralysis preoperatively. The outcome, after treatment by CT-guided percutaneous puncture and local chemotherapy, was retrospectively analyzed according to the preoperative and postoperative kyphotic angles and the Oswestry disability index (ODI). Results:, Forty-nine patients were followed up for from one year to 5 years and 8 months (average 35 months). All cases recovered, and there was no recurrence. Preoperatively, the kyphotic angle was 16.47°± 8.74°, and it had decreased to 13.35°± 8.02° by the final follow-up (t= 5.79, P < 0.001). The average ODI score had improved from 70.12 ± 22.24 to 12.72 ± 8.62 (t= 21.42, P < 0.001). Conclusion:, The majority of cases of lumbar and lumbosacral spinal TB can achieve satisfactory results with minimally invasive surgery. Its clinical application is therefore strongly recommended.

    F.E.S.C., PIER GIORGIO GOLZIO M.D.
    A patient required lead extraction for chronic draining sinus, due to abandoned leads. Preoperatively, the chest film showed a filament in the right pulmonary artery: it was the inner coil of an old atrial lead that, while remaining anchored to the auricle, slid outside the outer coil. By right subclavian approach, the old ventricular lead and the outer coil of the atrial lead were removed. Then, by right jugular approach, the freely floating end of theinner atrial coil was grasped by a pig-tail catheter, drawn back into the superior vena cava, exteriorized by a Lasso catheter, and finally extracted.

    Mueller C, Hansen G, Ballmann M, Schwerk N, Simon AR, Goerler H, Strueber M. Size reduction of donor organs in pediatric lung transplantation. Pediatr Transplantation 2010:14: 364,368. © 2009 John Wiley & Sons A/S. Abstract:, Lobar transplantation and peripheral segmental resection allow downsizing of larger lungs for use in smaller recipients, particularly with regard to pediatric patients on the high urgency waiting list. We studied the safety and outcome of these techniques in children. All pediatric patients who underwent reduced size LTx between January 2000 and March 2009 were retrospectively reviewed and compared with pediatric patients who underwent full size LTx during the same period. Patient characteristics, intra-operative variables, and post-operative morbidity and mortality were compared. Among 28 primary LTxs, 16 (57%) were performed in reduced size technique. Preoperatively, there was a trend toward a higher rate of mechanical ventilation and a higher capillary pCO2 in the reduced size group. Surgical procedures tended to be longer in that group. Post-operative complications, survival and functional parameters were comparable between both groups. Our study demonstrates that reduced size LTx in children is a reliable therapeutic option that provides results comparable to full size LTx. This technique might help to reduce waiting list mortality by expanding the donor pool in pediatric LTx. [source]


    Effectiveness of Adenoidectomy and Laser Tympanic Membrane Fenestration,

    THE LARYNGOSCOPE, Issue 2 2001
    Steven P. Cook MD
    Abstract Objective Adenoidectomy alone or with tonsillectomy (A±T) is an effective surgical intervention in the management of otitis media in children, especially when it is performed in conjunction with insertion of pressure equalization tubes (PETs). Otorrhea and persistent tympanic membrane (TM) perforation are frequent complications. This study evaluates the effectiveness of intermediate duration middle ear ventilation using laser tympanic membrane fenestration (LTMF) without tube insertion and as an adjunct to adenoidectomy in resolving middle ear disease within the first 90 days after surgery. Study Design This pilot study was a multicenter, prospective clinical cohort trial. Institutional review board approval and informed consent were obtained. The study involved four tertiary care pediatric otolaryngology departments. Fifty children (96 ears) were treated with LTMF in conjunction with A±T from June 1, 1998, through March 30, 1999. Ages ranged from 9 months to 12 years. Patients undergoing A±T who would have been recommended for PET insertion instead underwent middle ear ventilation with LTMF using the OtoLAMÔ device (ESC/Sharplan, Yokneam, Israel). Patients were seen at 30, 60, and 90 days postoperatively. Resolution of otitis media with effusion was determined by clinical examination, which included pneumatic otoscopy, audiometry, and tympanometry. Results Of the treated ears, 88%, 86%, and 83% had clinical resolution of middle ear disease at 30, 60, and 90 days, respectively. Preoperatively, 45% (n = 85) of ears had normal hearing; 92% (n = 49) had normal hearing at 90 days. Eighty-nine percent (n = 92) had type C2 or B tympanograms preoperatively, and 12% (n = 60) had type C2 or B at 90 days. Conclusion Laser tympanic membrane fenestration in conjunction with adenoidectomy was effective in restoring normal middle ear function at 90 days post-treatment in greater than 80% of children who otherwise may have had placement of PETs.

    Efficacy of Living Donor Liver Transplantation for Patients With Methylmalonic Acidemia

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 12 2007
    D. Morioka
    Application of liver transplantation to methylmalonic acidemia (MMAemia) is controversial because MMAemia is caused by a systemic defect of methylmalonyl-CoA mutase. The clinical courses of seven pediatric patients with MMAemia undergoing living donor liver transplantation (LDLT) were reviewed. Serum and urinary methylmalonic acid (MMA) levels were found to be significantly decreased after LDLT, whereas serum and urinary MMA levels did not return to normal in any patient. One patient died of sepsis 44 days after LDLT. The other six patients are currently doing well. All patients had preoperative history of acute metabolic decompensation and/or metabolic stroke. However, no episode of acute metabolic decompensation or metabolic stroke was observed postoperatively in any surviving patients. In the preoperative period, all patients showed lethargy and cognitive deficit, both of which were eradicated after LDLT in all surviving patients. Preoperatively, all patients were subjected to dietary protein intake restriction and tube feeding, and were administered several metabolism-correcting medications. The metabolism-correcting medications being administered remained mostly unchanged after LDLT, whereas protein restriction was liberalized and tube feeding became unnecessary in all surviving patients. In addition, physical and neurodevelopmental growth delay remained in all surviving patients during the observation period, which ranged from 4 to 21 months with a median of 10.5 months. [source]


    Combined radioguided occult lesion and sentinel node localization for breast cancer

    ANZ JOURNAL OF SURGERY, Issue 7 2004
    Joon Kim
    Introduction: The incidence of non-palpable breast lesions requiring intraoperative localization has greatly increased, particularly because of the widespread use of mammographic screening. These lesions have previously been localized preoperatively using hook-wire or carbon track techniques. In the era of increasing acceptance of sentinel node biopsy (SNB) a separate procedure would be required for sentinel node localization (SNL). The present study describes an experience with ultrasound guided radionucleotide occult lesion localization (ROLL) as a reliable alternative that enables SNL synchronously. Methods: Twenty-two patients with proven breast malignancy on core biopsy were enrolled in the present study. Preoperatively, technetium-99m was injected around the lesion under radiological guidance. A ,-probe was then used to locate the lesion and guide its surgical removal. Complete excision was then confirmed immediately by verifying minimal residual radioactivity in the cavity wall tissue. Appropriate SNB then proceeded. Results: The primary breast lesion was identified in all cases except in one, where the radiotracer was injected into the wrong site, giving a miss rate of 1/22 (4.5%). The average size of the tumour was 13 mm (range 6,22 mm) and the closest margins ranged from 0 (1 patient) to 22 mm (mean 7 mm). Two patients had inadequate margins and required further excision giving a re-excision rate of 2/21 (9.5%). SNB specimens included a median of 3.7 nodes/patient Conclusion: Radionucleotide occult lesion localization/SNL is a simple, accurate and reliable method of combining localization of impalpable breast lesions with the localization required for SNB. The miss and re-excision rates compare favourably with the needle-wire systems and carbon tracking techniques. There are significant resource efficiency and time advantages. [source]


    Prognostic significance of urokinase plasminogen activator receptor and its cleaved forms in blood from patients with non-small cell lung cancer

    APMIS, Issue 10 2009
    CHARLOTTE ELBERLING ALMASI
    Urokinase plasminogen activator (uPA) cleaves its three-domain cell surface receptor, uPAR, liberating domain I [uPAR(I)] and leaving the cleaved uPAR(II-III) on the cell surface. Both intact and cleaved uPAR can be shed from the cell surface. uPAR(I) was previously shown to be a prognostic factor in lung tumour extracts. Here we analyse uPAR forms in blood from patients with non-small cell lung cancer (NSCLC). Preoperatively sampled plasma/serum from 32 patients with NSCLC was analysed. Three time-resolved fluoroimmunoassays (TR-FIAs) measuring intact uPAR(I-III) (TR-FIA 1), uPAR(I-III) + uPAR(II-III) (TR-FIA 2) and uPAR(I) (TR-FIA 3) were applied. The Spearman rank correlations between plasma and serum levels of uPAR(I-III), uPAR(I-III) + uPAR(II-III), and uPAR(I) were 0.89, 0.94 and 0.68 respectively. Survival analysis demonstrated that high levels of all uPAR forms were associated with shorter survival. Adjusted for histological subtype high plasma uPAR(I-III) and uPAR(I) levels as well as serum uPAR(I) levels were significantly associated with shorter OS (hazards ratios = 4.3, 2.8 and 3.8 respectively). High blood levels of intact uPAR and its cleaved forms are associated with poor prognosis in NSCLC. [source]


    Destination Therapy: One-Year Outcomes in Patients With a Body Mass Index Greater Than 30

    ARTIFICIAL ORGANS, Issue 2 2010
    Laura A. Coyle
    Abstract Left ventricular assist devices (LVADs) are slowly gaining acceptance as the treatment of choice in appropriately selected patients with end-stage heart failure who are not transplant candidates. Obesity is a well-known risk factor for increased cardiovascular morbidity and mortality, and frequently can be the reason some patients are turned down for heart transplantation. Because of this experience in transplant patients, many centers have also been reluctant to offer these patients an LVAD for destination therapy (DT). Subsequently, the 1-year outcomes of obese patients receiving LVADs for DT at our center were reviewed. Fifty-eight consecutive patients (83% men) were implanted with HeartMate XVE (n = 22) or HeartMate II (n = 36) LVAD. Patients were divided into normal (body mass index [BMI] , 30 kg/m2, n = 38) and obese (BMI , 30 kg/m2, n = 20) groups according to their BMI. Preoperatively, there were statistically significant differences (P < 0.05) between normal and obese groups in age (65.9 years vs. 54.7 years), weight (72.9 kg vs. 107.5 kg), BMI (24.1 kg/m2 vs. 35.2 kg/m2), and incidence of diabetes (37% vs. 60%). At 1-year follow-up, there were no statistically significant differences (P > 0.5) between normal and obese groups: creatinine levels (1.4 vs. 1.5), New York Heart Association classification (1.2 vs. 1.6), and survival (63% vs. 65%). Our initial results demonstrate that morbidly obese patients with end-stage heart failure with a contraindication for transplant may successfully undergo implantation of an LVAD for DT. [source]


    Adnexectomy for benign pathology at vaginal hysterectomy without laparoscopic assistance

    BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 12 2002
    Shirish S. Sheth
    Of 166 consecutive women with a benign adnexal mass scheduled for vaginal hysterectomy with adnexectomy, the operation was successful in 158 (95%). Preoperatively, attempts were made to ascertain that adnexal mass was benign and either freely mobile or with only slightly restricted mobility. Laparotomy was required in eight women, in five for adhesions and in three for malignancy detected during the operation. No woman required laparoscopic-assisted surgery. The 158 women who had successful vaginal hysterectomy with adnexectomy were compared with 100 similar women who had a laparotomy performed by same single operator. The vaginal group had a lower morbidity, speedier recovery and shorter hospital stay. [source]


    Valproate induces reversible factor XIII deficiency with risk of perioperative bleeding

    ACTA NEUROLOGICA SCANDINAVICA, Issue 2 2003
    B. Pohlmann-Eden
    The antiepileptic drug valproic acid (VPA) induces subclinical changes in both the intrinsic and extrinsic coagulation system. However, fatal bleeding is very rare. This study reports a 39-year-old patient who underwent selective amygdalohippocampectomy because of drug-resistant temporal lobe epilepsy. Preoperatively, the patient was on a combined therapy with VPA and topiramate, and routine coagulation laboratory parameters were entirely normal. Epilepsy surgery was immediately followed by severe intracranial bleeding events which promped repeated craniectomy. Extensive laboratory analyses revealed a factor XIII activity level of 17%, indicating factor XIII deficiency confirmed by a reduced XIIIA-antigen. After termination of treatment with VPA, factor XIII levels returned to normal. Control examinations after 9 and 24 months showed normal range values for all coagulation parameters, including factor XIII, platelet function, and von Willebrand factor. To our knowledge, this case is the first description of a well-documented, clinically relevant transient factor XIII-deficiency syndrome related to VPA treatment. [source]


    Retinal sensitivity and fixation changes 1 year after triamcinolone acetonide assisted internal limiting membrane peeling for macular hole surgery , a MP-1 microperimetric study

    ACTA OPHTHALMOLOGICA, Issue 6 2010
    Hakan Ozdemir
    Acta Ophthalmol. 2010: 88: e222,e227 Abstract. Purpose:, To evaluate microperimetric changes 1 year after macular hole surgery with triamcinolone acetonide assisted internal limiting membrane (ILM) peeling. Methods:, Twenty-two eyes of 22 patients with stage 3 and 4 idiopathic macular holes of <6 months' duration underwent vitrectomy with triamcinolone acetonide assisted ILM peeling. Best corrected visual acuity (BCVA) (logarithm of the minimum angle of resolution), and central retinal sensitivity were documented before and 1, 3, 6, and 12 months after surgery. Macular sensitivity (mean sensitivity in decibels -dB), and stability and location of fixation (preferred retinal locus) were determined using MP-1 microperimetry (Nidek). The MP-1 microperimetry sensitivity map was overlaid onto infrared images recorded on a Heidelberg scanning laser ophthalmoscope using dedicated MP-1 software to evaluate the fixation location before surgery. Anatomical success was evaluated with optical coherence tomography (OCT). Optical coherence tomography scans were recorded on an OCT 3000 scanner. Results:, Anatomical success was achieved in all 22 eyes. All patients completed 1 year follow-up. No recurrence of macular hole was seen in any patients in the follow-up period. The mean BCVA improved from 0.75 ± 0.2 before surgery to 0.31 ± 0.1 logMAR at the last visit (p < 0.001). Mean sensitivity improved from 3.7 ± 0.6 to 5.3 ± 1.0 dB at the last visit (p < 0.001). Before surgery, the preferred retinal locus was located on the margin of the hole in all, in 18 eyes on its upper part and in four eyes to the side or on its lower part. Preoperatively, 12 eyes were stable and 10 were relatively unstable, but 12 month after surgery, fixation stability had improved, and 20 eyes were stable and two were relatively unstable. Conclusions:, MP-1 microperimetry sensitivity map overlaid onto an infrared image using dedicated MP-1 software can be used successfully to evaluate fixation location in patients with a macular hole before surgery. With microperimetry findings, we can also measure functional macular changes more precisely than using BCVA alone after macular hole surgery. Our results also showed that retinal sensitivity and fixation properties were improved after vitrectomy with triamcinolone acetonide assisted ILM peeling in patients with idiopathic macular hole.

    Mitomycin-C-augmented deep sclerectomy in patients with primary open-angle glaucoma and exfoliation glaucoma: a 1-year prospective study

    ACTA OPHTHALMOLOGICA, Issue 1 2010
    Minna Ollikainen
    ABSTRACT. Purpose:, To investigate the efficacy and safety of mitomycin C (MMC)-augmented deep sclerectomy with implant (DSCI) in patients with primary open-angle glaucoma (POAG) and exfoliation glaucoma (ExG). Methods:, A total of 68 eyes of 68 patients with POAG and ExG were enrolled consecutively to undergo DSCI with MMC (0.4 mg/ml for 2 min). The intraocular pressure (IOP), number of antiglaucoma medications, neodymium:yttrium-aluminum-garnet (Nd:YAG) laser goniopunctures and complications were compared postoperatively. Surgery was considered as a complete success when IOP was < 18 mmHg without antiglaucoma medication. Results:, Preoperatively, the mean IOPs were 23.1 ± 5.8 and 25.4 ± 8.3 mmHg, and 13.8 ± 6.1 and 11.2 ± 5.6 mmHg in the POAG and ExG groups, respectively, at 12 months. 77.4% and 75.7% of surgeries were a complete success in the POAG and ExG groups, respectively [not significant (NS)]. Five patients (16.1%) in the POAG group but none in the ExG group (0%) were receiving antiglaucoma medication at 12 months (NS). Nd:YAG laser goniopuncture was performed in 29.0% of eyes in the POAG group and in 55.6% of eyes in the ExG group (p = 0.047). Postoperatively, choroidal detachment occurred in 16.1% of eyes in the POAG group and in 10.8% of eyes in the ExG group (NS). We encountered no serious complications related to MMC use. Conclusion:, DS with MMC augmentation appears to be equally effective in ExG and POAG patients in lowering IOP to target levels, at least in the short term, with few immediate postoperative complications.

    Molteno aqueous shunt as a primary surgical intervention for uveitic glaucoma: long-term results

    ACTA OPHTHALMOLOGICA, Issue 1 2010
    Marja-Liisa Vuori
    Abstract. Purpose:, To evaluate the efficacy of Molteno aqueous shunt as a primary surgical treatment in uveitic glaucoma. Methods:, Nonrandomized, interventional, retrospective clinical study. The intraocular pressure (IOP), survival rate and complications were analyzed in 30 patients with uveitic glaucoma treated with Molteno implant. Results:, The mean follow-up time was 59.3 ± 18.4 months. Preoperatively, the mean ± SD IOP was 32.8 ± 7.5 mmHg (range 20,48), and the mean number of medications was 3.1 ± 0.6. The mean IOP decreased significantly (p < 0.001) to 17.7 and 15 mmHg at 3 and 6 months postoperatively. The mean number of medications decreased statistically significantly (p < 0.001) from the preoperative number 3.1 to 1.9 three months postoperatively. The number of medications continued to decrease significantly up to 3 years postoperatively. The qualified success rate (Kaplan,Meier estimate) was 97%, 93%, 90% and 85% at 1, 2, 3 and 4 years, respectively. Two patients failed because of hypotony, two patients developed conjunctival erosion and one patient had corneal decompensation. Conclusions:, Molteno aqueous shunt as the first glaucoma procedure decreased IOP effectively in uveitic glaucoma. Even after 4 years, the survival estimate was quite high. The IOP decreased continuously during the first year after the surgery, and the medication was slowly tapered even up to 3 years postoperatively. It is suggested that it may be possible to postpone further surgical intervention during the first postoperative year after Molteno implantation even if the IOP is not quite optimal. [source]

    Abstract. Purpose:, In this retrospective case series, we studied the effect of ,heavy' silicone oil on persisting macular holes. Patients with macular holes that failed to close after conventional macular hole surgery were retreated with the longterm internal tamponade Densiron-68®. Methods:, Twelve patients with primary macular holes that persisted after pars plana vitrectomy, peeling of the internal limiting membrane and internal gas tamponade with SF6 (sulphur hexafluoride) were retreated with heavy silicone oil, Densiron-68®, in the University Eye Hospital, Cologne. After 1.5,4 months the Densiron-68® was removed. Best corrected visual acuity (VA), slit-lamp examination, binocular fundus examination and optical coherence tomography (OCT) were used for evaluation pre- and postoperatively. The follow-up period was 3,7 months. Results:, Preoperatively, all patients displayed full-thickness macular holes, with a mean size of 502.25 ,m (± 129.39 ,m). Postoperatively, 11 of 12 macular holes were closed. One patient experienced a reopening of the macular hole. Mean VA was 20/250 (1.07 ± 0.22 logMAR) prior to treatment with Densiron-68® and 20/160 (0.84 ± 0.24 logMAR) postoperatively. Visual acuity increased from baseline in nine patients and decreased in one. Conclusions:, Retreatment of persisting macular holes with the heavy, longterm tamponade Densiron-68® resulted in anatomical closure of the hole in 11 of 12 cases. This result was accompanied by a functional improvement in VA in nine of 12 patients. [source]


    Glaucoma associated with KPros

    ACTA OPHTHALMOLOGICA, Issue 2009
    K HILLE
    Purpose Glaucoma is one of the most serious problems in Keratoprostheses. Already glaucoma is very frequent in patients with severe changes of the ocular surface requiring keratoprosthesis surgery. About 50% of those patients have pre-existing secondary glaucoma. Preoperatively all efforts should be done to detect its presence very early on. In KPro detection of glaucoma with traditional aids is difficult. A rough estimation of the tension by digital palpation will be the only available method. All indirect clues such as the medical history of glaucoma, echographic signs of disc cupping and anterior synechiae and examination of the visual field should be considered. Methods The incidence of postoperative secondary glaucoma vary among the different kinds of prostheses according to the surgery affecting the anterior segment and the long term anatomic results. In Osteo-Odonto-Keratoprostheses (OOKP) the most vision threatening complication is a primary or secondary glaucoma, due to the extended interventions required in the anterior segment. In Boston Keratoprostheses the risk seems to be somehow less. Results As the absorption of topical anti-glaucomatous medication will not reach the inner eye because of the anatomic barrier in KPro the only promising possibilities of treatment are systemic carbonic anhydrase inhibitors, different kinds of aqueous shunts and endo-cyclo-laserphotocoagulation. Conclusion Glaucoma is still a mayor problem in KPro. PS: This lession will be presented at the KPro-Meeting!! [source]


    The retinal nerve fiber layer and the optic nerve head morphology after glaucoma surgery

    ACTA OPHTHALMOLOGICA, Issue 2009
    T GRACNER
    Purpose To detect and quantify changes in the retinal nerve fiber layer (RNFL) and the optic nerve head (ONH) morphology after glaucoma surgery. Methods 13 eyes of 13 patients with open-angle glaucoma in which goniotrephining with scleral flap without intraoperative antimetabolites for progressive glaucoma damage was done were included in this prospective study. Before and 6 months after the surgery: the intraocular pressure (IOP) was measured, the thicknes of the RNFL was measured with a scanning laser polarimeter (GDx VCC), the confocal scanning laser ophthalmoscopy measurements of ONH with Heidelberg retina tomograph (HRT 3) were performed and the visual field was tested with Humphrey Field Analyser. Results The mean IOP before surgery was 24.5 ? 2.3 mmHg decreasing 6 months after to a mean of 13.9 ? 3.0 mmHg (p<0.05). The RNFL measurements with GDx VCC revealed no differences between the mean TSNIT Avarage (p=0.383), mean Superior Avarage (p=0.756) and mean Inferior Avarage (p=0.269) before and after surgery. The ONH measurements with HRT 3 revealed postoperatively a significant increase in the mean Rim Area, Rim Volume and Cup Shape Measure, whereas Cup Area, Cup Volume and Linear Cup/Disc Ratio decreased (p<0.05). There were no differences between the mean Height Variation Contour (p=0.678) and Mean RNFL Thickness (p=0.064) before and after surgery. Preoperatively the mean value of the Mean Deviation on automated perimetry was ,18.82 ? 8.5 dB improving 6 months postoperatively to a mean of ,16.63 ? 7.9 dB (p<0.05). Conclusion Our study demonstrated the beneficial effect of IOP reduction obtained with glaucoma surgery on visual field indices and ONH parameters evaluated by HRT 3. [source]


    Results from the International Cataract Surgery Outcomes Study

    ACTA OPHTHALMOLOGICA, Issue thesis2 2007
    Jens Christian Norregaard MD
    Abstract It is widely accepted that cataract extraction with intraocular lens implantation is a highly effective and successful procedure. However, quality assessments and studies of effectiveness should still be undertaken. As with any surgical treatment modality, complications may occur, leading to suboptimal outcomes, additional health costs and deterioration in patients' functional capacity. International variation in clinical practice patterns and outcomes can serve as important pointers in the attempt to identify areas amenable to improvements in quality and cost-effectiveness. Once demonstrated, similar clinical results obtained in different health care systems can improve the level of confidence in a clinical standard against which the quality of care can be evaluated. The International Cataract Surgery Outcomes Study was established in 1992. The objective of this international comparative research project was to compare cataract management, outcomes of surgery and quality of care in four international sites. The study was conducted in the 1990s, since when many developments and refinements have emerged within cataract surgery. The actual figures reported in this thesis may no longer be of specific relevance as a decade has passed since their collection. However, the research questions and methods used in the study are still highly important and justify the publication of this report. The report deals with problems related to quality assessment, benchmarking, and the establishment and design of nationwide clinical databases , issues that are currently the focus of much attention. Moreover, the problems related to cross-national comparisons are increasingly relevant as more international databases are established. The study makes suggestions on how to report and compare objective as well as subjective criteria for surgery. The issue of how to report subjective criteria is a particular subject of current discussion. Four sites with high-quality health care systems were examined in this study: the USA, Denmark, the Province of Manitoba (Canada), and Barcelona (Spain). The design of the international research programme was based on methods developed by the US National Cataract Surgery Outcomes Study conducted by the US Cataract Patients Outcomes Research Team. The International Cataract Surgery Outcomes Study comprised three separate studies: a survey of ophthalmologists; a prospective cohort study, and a retrospective register-based cohort study. The survey study was based on data generated by a self-administered questionnaire completed by ophthalmologists in the four study areas. The questionnaire examined routine clinical practice involving patients considered for cataract surgery, and included questions on anaesthesia, monitoring and surgical techniques. The prospective cohort study was a large-scale, longitudinal observational study of patients undergoing first-eye cataract surgery in each study site. Patients were sampled consecutively from multiple clinics and followed for 4 months postoperatively. The retrospective cohort study was based on the Danish National Patient Register and claims data from the USA. This study could not be carried out in Barcelona or Manitoba as no suitable administrative databases were available. The papers based on register databases deal with retinal detachment and endophthalmitis but are not included in this thesis as the material was previously reported in my PhD thesis. The application of the studies was highly co-ordinated among the four sites and similar methods and instruments were used for data collection. The development of the data collection strategy, questionnaires, clinical data forms and data analyses were co-ordinated through weekly telephone conferences, annual in-person conferences, correspondence by mail or fax, and the exchange of sas programs and data files via the Internet. The survey study was based on responses from 1121 ophthalmologists in the four sites and results were presented in two papers. Within the previous year the participating ophthalmologists had performed a total of 212 428 cataract surgeries. With regard to preoperative ophthalmic testing, the present study reveals that refraction, fundus examination and A-scanning were performed routinely by most surgeons in all four sites. Other tests were reported to be performed routinely by some surgeons. It is unclear why any surgeon would use these other tests routinely in cataract patients with no ocular comorbidity. It appears that if this recommendation from the US Clinical Practice Guidelines Panel was broadly accepted, the use of these procedures and costs of care could be reduced, especially in Barcelona, the USA and Canada. Restricted use of medical screening tests was reported in Denmark. If this restricted screening were to be implemented in the USA, Canada and Barcelona, it would have significant resource implications. The most striking finding concerned the difference in monitoring practice between Denmark and each of the other three sites. In Denmark, monitoring equipment is seldom used and only occasionally is an anaesthesiologist present during cataract surgery. By contrast, in the other study sites, the presence of an anaesthesiologist using monitoring equipment is the norm. Adopting the Danish model in other sites would potentially yield significant cost savings. The results represent part of the background data used to inform the decision to conduct the two large-scale, multicentre Studies of Medical Testing for Cataract Surgery. The current study is an example of how surveys of clinical practice can pinpoint topics that need to be examined in randomized clinical trials. For the second study, 1422 patients were followed from prior to surgery until 4 months postoperatively. Preoperatively, a medical history was obtained and an ophthalmic examination of each patient performed. After consent had been obtained, patients were contacted for an in-depth telephone interview. The interview was repeated 4 months postoperatively. The interview included the VF-14, an index of functional impairment in patients with cataract. Perioperative data were available for 1344 patients (95%). The 4-month postoperative interview and clinical examination were completed by 1284 patients (91%). Main reasons for not re-evaluating patients were: surgery was cancelled (3%); refusal to participate (2%); lost to follow-up (1%), and death or being too sick (1%). The results have been presented in several papers, of which four are included in this thesis. One paper compared the preoperative clinical status of patients across the four sites and showed differences in both visual acuity (VA) and VF-14 measures. The VF-14 is a questionnaire scoring disability related to vision. The findings suggest that indications for surgery in comparable patients were similar in the USA and Denmark and were more liberal than in Manitoba and Barcelona. The results highlight the need to control for patient case mix when making comparisons among providers in a clinical database. This information is important when planning national databases that aim to compare quality of care. A feasible method may be to use one of the recently developed systems for case severity grading before cataract surgery. In another paper, perioperative clinical practice and rates of early complications following cataract surgery were compared across the four health care systems. Once again, the importance of controlling for case mix was demonstrated. Significant differences in clinical practice patterns were revealed, suggesting a general trend towards slower diffusion of new medical technology in Europe compared with North America. There were significant differences across sites in rates of intra- and early postoperative events. The most important differences were seen for rates of capsular rupture, hyphaema, corneal oedema and elevated pressure. Rates of these adverse events might potentially be minimized if factors responsible for the observed differences could be identified. Our results point towards the need for further research in this area. In a third paper, 4-month VA outcomes were compared across the four sites. When mean postoperative VA or crude proportions of patients with a visual outcome of <,0.67 were compared across sites, a much poorer outcome was seen in Barcelona. However, higher age, poorer general health status, lower preoperative VA and presence of ocular comorbidity were found to be significant risk factors associated with increased likelihood of poorer postoperative VA. The proportions of patients with these risk factors varied across sites. After controlling for the different distributions of these factors, no significant difference remained across the four sites regarding risk of a poor visual outcome. Once again the importance of controlling for case mix was demonstrated. In the fourth paper, we examined the postoperative VF-14 score as a measure of visual outcomes for cataract surgery in health care settings in four countries. Controlling for case mix was also necessary for this variable. After controlling for patient case mix, the odds for achieving an optimal visual function outcome were similar across the four sites. Age, gender and coexisting ocular pathology were important predictors of visual functional outcome. Despite what seemed to be an optimal surgical outcome, a third of patients still experienced visual disabilities in everyday life. A measure of the VF-14 might help to elucidate this issue, especially in any study evaluating the benefits of cataract surgery in a public health care context. [source]


    Medial canthal tendon repair for moderate to severe tendon laxity

    CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 2 2004
    Colin I Clement MB BS PhD
    Abstract Background:,Medial canthal tendon laxity is a common cause of epiphora and ocular irritation. It is difficult to treat due to the proximity of the lower canaliculus and punctum to the tendon. Methods:,The results of a prospective series of patients with involutional medial canthal tendon laxity between 1997 and 2002 were reviewed. Symptoms and measured laxity were recorded before and after medial canthal tendon repair. The medial canthal tendon was routinely repaired through a cut along the lid margin extending from the punctum medially. This avoids a vertical cut onto the anterior lamella of the eyelid, which is useful if a skin graft is required. Results:,Twenty lower eyelid medial canthal tendon repairs were performed on 17 patients. Preoperatively, the lower punctum in all patients was able to be distracted to the medial limbus or further and in 50% of cases, the lower lid punctum was able to be distracted to the pupil midline or further. Postoperatively all patients had reduction of their medial canthal tendon laxity. Postoperatively in 85% of cases the lower punctum was not able to be distracted beyond the medial limbus; however, 15% of cases still had significant residual laxity. Eighty-five per cent of patients reported improvement in symptoms. Conclusions:,This is an effective procedure in the majority of patients with moderate to severe medial canthal tendon laxity; however, residual lower lid laxity persisted in some patients. [source]


    Maxillary Implants Loaded at 3 Months after Insertion: Results with Astra Tech Implants after up to 5 Years

    CLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH, Issue 3 2001
    Helmut Steveling DMD
    ABSTRACT Background: To date, clinical studies have mainly focused on early loading of mandibular implants. Recently, there has also been considerable interest in early loading of maxillary implants. Purpose: The purpose of this article is to report the outcome of maxillary implants loaded after a 3-month healing period and followed up to 5 years. Materials and Methods: Seventeen patients (11 males and 6 females) received 44 Astra Tech implants (Molndal, Sweden) for treatment of single-tooth (13 cases) and partial edentulism (9 cases). The patients were followed up to 5 years after implant placement:50% of the implants were followed for 3 years and 16% have been followed throughout the observation period. Preoperatively, bone height and width were assessed on radiographs. Marginal bone loss was recorded on intraoral radiographs annually. Results: No implant was lost during the observation period. The average marginal bone loss was 0.5 ± 0.7 mm after 1 year, 0.6 ± 0.7 mm after 3 years, and 0.9 ± 1.6 mm after 5 years. There were no soft-tissue or prosthetic failures recorded during the observation period. Conclusion: Early loading of Astra Tech implants was highly successful in maxillary partial and single-tooth cases followed up to 5 years in function. [source]


    Relation between change of hearing and (modified) Amsterdam Inventory for Auditory Disability and Handicap Score

    CLINICAL OTOLARYNGOLOGY, Issue 6 2004
    A.G.W. Meijer
    This study investigates the test,retest distributions and the interval for true score change of the (modified) Amsterdam Inventory for Auditory Disability and Handicap [(m)AIAD], when the latter is used to measure the effect of an intervention. In a previous study the reliability and validity of the (m)AIAD in a cohort of hearing impaired patients were found to have satisfactory high values. In this prospective study, 66 patients underwent a tympanoplasty operation. Preoperatively and postoperatively pure tone audiometry was performed, and at the same time the subjective hearing ability was established by means of the (m)AIAD. The correlation between threshold change and score change was 0.35 (Pearson's r). Scores on the (m)AIAD had to change by at least 16 to be qualified as a true change. For only nine of 66 subjects this criterion was fulfilled. No clear relation exists, except for these nine subjects, between threshold change and score change in this patient population. The study also shows that disability questionnaires have their limitations, when using them to measure the result of a medical intervention in an individual patient. [source]


    Benign lesions of the vocal folds: a masquerade

    CLINICAL OTOLARYNGOLOGY, Issue 4 2000
    P.J.P. Poels
    Objective. The aim of this study is to give an analysis of the nature of benign vocal fold lesions with an indication for microlaryngoscopy that are found in a general ENT clinic. Patients and methods. Retrospectively, pre- and peroperative data from 177 successive patients were examined. Results. The male : female distribution was 1 : 3. Preoperatively, bilateral lesions were found in 53%, changing into 82% at peroperative examination. Nodules, polyps, Reinke's oedema and intracordal lesions,such as sulcus vocalis, vergeture and cysts,were the most frequently found lesions. The intracordale lesions were easily missed at preoperative examination. Half of the patients had occupational voice use. Conclusion. In spite of laryngostroboscopy, the vocal fold lesions could not always be diagnosed correctly. It is recommended to perform a diagnostic microlaryngoscopy in cases of unclear dysphonia and to examine both vocal folds peroperatively. It may be advisable to develop a new terminology for vocal fold lesions, based on their functional behaviour. At this, stroboscopy can be completed by videokymography. [source]
